A widespread, but very poorly known species (EOO 16 344 km²). It is possibly threatened by habitat loss and degradation, but due to a lack of recent field observations nothing is known about its population size, structure and trends. Therefore its risk of extinction cannot be assessed at present.

The threats to this taxon are not known. It is probably threatened by habitat loss to mining on the Namaqualand coast, where extensive, highly destructive open-cast mining has led to the loss and degradation of large areas of coastal duneveld. Further south it is likely to be threatened by habitat loss to coastal development.

Population

This species is known from only a handful of historical records, and was last observed in 1952. Adenogramma species are cryptic and very easily overlooked, but the lack of recent records are concerning. Field surveys are needed to relocate it in the wild. Historical records suggest that it has a fairly wide distribution range, but based on available data, the number of extant subpopulations, population size and trends cannot be estimated.
